address? - CORRECT ANSWER - FF00::/8
QUESTION 19
What are two reasons that cause late collisions to increment on an Ethernet
interface? (Choose two.) - CORRECT ANSWER - when one side of the
connection is configured for half-duplex
when the cable length limits are exceeded
QUESTION 20
What is a benefit of using a Cisco Wireless LAN Controller? - CORRECT
ANSWER - It eliminates the need to configure each access point individually
Question 21
Which action is taken by switch port enabled for PoE power classification
override? - CORRECT ANSWER - If a monitored port exceeds the maximum
administrative value for power, the port is shutdown and err-disabled.
QUESTION 22
What occurs to frames during the process of frame flooding? - CORRECT
ANSWER - Frames are sent to every port on the switch in the same VLAN except
from the originating port
QUESTION 23

, QUESTION 24
Which action must be taken to assign a global unicast IPv6 address on an interface
that is derived from the MAC address of that interface? - CORRECT ANSWER -
enable SLAAC on an interface
QUESTION 25
Several new coverage cells are required to improve the Wi-Fi network of an
organization. Which two standard designs are recommended? (Choose two)? -
CORRECT ANSWER - Cells that overlap one another are configured to use
nonoverlapping channels.
For maximum throughput, the WLC is configured to dynamically set adjacent
access points to the channel.
QUESTION 26
How do TCP and UDP differ in the way they provide reliability for delivery of
packets? - CORRECT ANSWER - TCP provides flow control to avoid
overwhelming a receiver by sending too many packets at once, UDP sends packets
to the receiver in a continuous stream without checking.
